  • Determine $DISPLAY socket name on OS X 10.6?

    - by Nate
    I'm looking to do something that's a little odd. I'm SSH'ing from a server to a Snow Leopard client to start an X11 data display process. In other words, SSH's X11 forwarding isn't what I want. I can do: client$ echo $DISPLAY /tmp/launch-SOMETHING/org.x:0 client$ ls -l $DISPLAY srwx------ 1 myuser wheel 0 Dec 9 15:47 /tmp/launch-SOMETHING/org.x:0 And, when I do: server$ ssh myuser@client client$ export DISPLAY=/tmp/launch-SOMETHING/org.x:0 client$ xterm I happily get my xterm. What I need, then, is some way to find out the correct value for $DISPLAY in my ssh session. From what I've read, $DISPLAY is set by launchd, but I haven't found any way to see that value. If it matters, I know that when my process connects from $server to $client, $client will logged in to the terminal as the same user.

  • SQL-Server 2008 : Table Insert and Range Check ?

    - by LB .
    I'm using the Table Value constructor to insert a bunch of rows at a time. However if i'm using sql replication, I run into a range check constraint on the publisher on my id column managed automatically. The reason is the fact that the id range doesn't seem to be increased during an insert of several values, meaning that the max id is reached before the actual range expansion could occur (or the id threshold). It looks like this problem for which the solution is either running the merge agent or run the sp_adjustpublisheridentityrange stored procedure. I'm litteraly doing something like : INSERT INTO dbo.MyProducts (Name, ListPrice) VALUES ('Helmet', 25.50), ('Wheel', 30.00), ((SELECT Name FROM Production.Product WHERE ProductID = 720), (SELECT ListPrice FROM Production.Product WHERE ProductID = 720)); GO What are my options (if I don't want or can't adopt any of the proposed solution) ? Expand the range ? Decrease the threshold ? Can I programmatically modify my request to circumvent this problem ? thanks.

  • How do you synchronise huge sparse files (VM disk images) between machines?

    - by chrisdew
    Is there a command, such as rsync, which can synchronise huge, sparse, files from one linux server to another? It is very important that the destination file remains sparse. It may be longer (but not bigger) than the drive which contains it. Only changed blocks should be sent across the wire. I have tried rsync, but got no joy. groups.google.com/group/mailing.unix.rsync/browse_thread/thread/94f39271980513d3 If I write a programme to do this, am I just reinventing the wheel? http://www.finalcog.com/synchronise-block-devices Thanks, Chris.

  • Url for search withing Exchange Server OWA

    - by Martin Vobr
    I can easily create url for searching the Internet for specific term: http://www.bing.com/search?q=example Is is possible to create a similar url for searching my Exchange server mailbox using Outlook Web App? Something like: http://my.exchange.server.tld/owa/search.aspx?q=example EDIT Some of comments asked for target, so here is the clarification: There is a web-based backoffice system which includes customer's email addresses. I want to provide an easy way to show emails related to this customer in a support mailbox. Adding a link to an OWA search result page seemed a way to accomplish quickly. I can lookup emails either via EWS or IMAP. I wanted to reuse OWA for displaying them instead of reinventing the wheel. If creating a search link is not possible what would be best alternative approach? I'm thinking about getting message list via EWS/IMAP, showing them and (at least now) redirecting to OWA in order to display the message content.

  • Creating encrypted database for work

    - by Baldur
    My boss posed this problem to me: Encrypted: We need an encrypted database for miscellanious passwords we use at work that are currently only in people's head. Easily accessable: Someone needs to be able to quickly access specific passwords, possibly at hectic moments. This requires any sort of public key management (keeping it on a USB key in a sealed envelope?) to be relatively easy. Access control: The system should have groups of passwords where only specific people have access to specific groups. Recoverability: We need to make sure passwords from one group aren't lost even if the only users with direct access quit or pass away—hence we need some way where (for example) any two members of senior management may override the system (see the treshold link below) and retrieve all the passwords with their key. The first thing that jumped into my mind was some form of threshold and asymmetric cryptography but I don't want to reinvent the wheel, are there any solutions for this? Any software should preferrably be free and open-source.

  • Unix: sleep until the specified time

    - by aix
    Is there a (semi-)standard Unix command that would sleep until the time specified on its command line? In other words, I am looking for something similar to sleep that would take wakeup time rather than duration. For example: sleeptill 05:00:00 I can code something up but would rather not re-invent the wheel if there's already something out there. Bonus question: it would be great if it could take the timezone (as in sleeptill 05:00:00 America/New_York). edit Due to the nature of what I am doing, I am looking for a "sleep until T" rather than "run command at T" solution. edit For the avoidance of doubt, if I run the command at 18:00 and tell it to wake up at 17:00, I expect it to sleep for 23 hours (or, in some corner cases having to do with daylight savings time, for 22 or 24 hours.)

  • Enable click-and-drag scrolling in Windows 8 / Metro?

    - by jdm
    In Windows 8 (Metro interface) I find myself trying to click and drag the background to scroll again and again, which does not work (I'm using a mouse, not touch). Also, scrolling with the scroll wheel, the bottom scrollbar, or the cursor keys is not nearly as smooth as I've seen in videos, or on tablets. Is there any way to enable smooth kinetic scrolling with the mouse? So that I can click and drag lists or multi-screen displays around? I remember seeing this in a video. I'm not sure if there was some third-party tool involved or not.

  • rss downloader script

    - by The Digital Ninja
    I have a Synology NAS that is powered by linux at my house. I'm looking to set up a cron script to check a group of rss feeds and auto download new video podcasts to a shared folder. I can do most of the scripting, such as deleting files older than 3 weeks and the wget parts. But I'm not sure how to parse the rss feed and check dates to only grab the latest. I figured its best not to re-invent the wheel and surly someone out there has a command line rss downloader or some such script. Any ideas?

  • Creating a webserver from scratch

    - by Val
    I know this is going to sound a humongous task and many of you would think why in the world would you want to do so or why re-invent the wheel. However I just want a project I can work on the side see how it goes and experiment ( I got a thirst for learning something new and this is a great challenge). Question Where would I start creating a server-side scripting like php, asp and (now) node.js I would like to have a few examples, and most importantly a CODEX/documentation where I can learn and find out more how it works. I guess I am asking for directions where to go to read and find out more about this. Many thanks,

  • puppet onlyif specified nodes

    - by Valintinr
    I'm trying to write a puppet template. I have a puppet-master and a few puppet-agents and they all must be divided. I think it's good to do this by the node's hostname. But when I tried to do this I've encountered an error "puppet-agent[169037]: (/Stage[main]//Exec[adduser]) Could not evaluate: Could not find command 'ru1'" see code below exec { 'adduser': command => 'sudo adduser -m -p pawSfQewWrUAA test -G wheel', path => [ '/bin','/usr/bin' ], onlyif => "$hostname == ru1" } I need to specify this task for only one node with the hostname ru1. So have can I do this? Thanks.

  • Trying to reinstalling .net framework 4 on windows server 2003 SP2

    - by LBR
    I had a problem with an application that was using .net framework 4. So I tried to fix the installation but it didn't solved. So I proceed to uninstall the framework and install it again. But then the problems started... the setup just wouldn't finish to download the framework. So i tried the full installer, and then it got stuck (freezes) at "installing client profile"... The server works well but the installation progress bar just stays at the same place (but the "wheel" keeps turning, like it was doing something, but stays like this for hours...) I tried the .net clean unistall software but the problem remains. I'm all out of ideas... I've searched the web but couldn't solve the problem with any solution I found... Any ideas on how to force the installation?

  • Embed Powershell prompt in Windows 7 desktop

    - by EricRRichards
    On Linux (last time I did this was with Compiz on Ubuntu 11), I like to have a transparent console window anchored to the desktop, so I can get to a shell just by clicking out of whatever I'm doing and don't have to play with with moving/resizing windows. I'd like to do something similar on Windows 7/Server 2008. I could probably write up a quick little app in .Net that would run fullscreen and have a powershell terminal embedded in it, but, if somebody has already created something sufficient, or there is some other hackery to do this, I don't want to reinvent the wheel. Another possibility could be a Quake-style pulldown console, similar to Guake (guake.org).

  • Fedora: "Login Incorrect"

    - by darkblackcorner
    I've just set up a minimal install on my netbook (the default was too resource hungry, so I figured I'd customize the install and learn something about linux at the same time!) No problems logging in as root, but when I create a new user and try to login as them I just get the "Login incorrect" error. I'm certain the password is correct, though the secure log displays an authentication error. Am I missing a permission somewhere? useradd test usermod -p [pwd] test Shell is added automatically I think (checking password file says shell is /bin/bash) I've tried adding the user to the sudo-ers group usermod -a -G wheel which doesn't help. I've kept the password simple in order to rule out human error.

  • Why my USB mouse get suspended after 3 seconds of inactivity?

    - by Vi.
    Mouse's bottom LED goes off after 3 seconds after connection and cursor movements and wheel stops. Pressing any button, reconnecting or resetting USB device resumes it for another 3 seconds (when resumed by pressing button, this event does no go to X). This happens when using any of USB ports. This mouse works well with other computer with Linux. It was working well before. Why can it happen? How to fix it? Update: It happens only if laptop is on battery. Answer: this is caused by powersaving done by laptop-mode-tools. To temporary turn off powersaving one can use for i in /sys/bus/usb/devices/*/power/control; do echo on > $i; done

  • Recommend a desktop app to monitor port 80 on servers

    - by busyone
    Hello, I did some googling but was unsuccessful, so I am posting here. I am looking to get an app (preferably free/open source) to monitor my servers on port 80 that would send me an email/text when some predefined timeout triggers. I could probably write something in VB to do this but i am burried with projects, why reinvent the wheel. I know there are services out there that want you to pay $5/month to do so, I was thinking about a Windows app that would sit on my computer and simply monitor predefined list of IPs on port 80. Thanks!

  • Automatically kill processes that over time uses 95%+ of resources? Ubuntu

    - by data_jepp
    I don't know about you're computer but when mine is working properly no process is sucking 95%+ over time. I would like to have some failsafe that kills any processes behaving like that. This comes to mind because when I woke up this morning my laptop had been crunching all night long on a stray chromium child process. This can probably be done as a cron job, but before I make it a full time job creating something like this I'd thought I should check here. :) I hate reinventing the wheel.

  • DropDownList and SelectListItem Array Item Updates in MVC

    - by Rick Strahl
    So I ran into an interesting behavior today as I deployed my first MVC 4 app tonight. I have a list form that has a filter drop down that allows selection of categories. This list is static and rarely changes so rather than loading these items from the database each time I load the items once and then cache the actual SelectListItem[] array in a static property. However, when we put the site online tonight we immediately noticed that the drop down list was coming up with pre-set values that randomly changed. Didn't take me long to trace this back to the cached list of SelectListItem[]. Clearly the list was getting updated - apparently through the model binding process in the selection postback. To clarify the scenario here's the drop down list definition in the Razor View:@Html.DropDownListFor(mod => mod.QueryParameters.Category, Model.CategoryList, "All Categories") where Model.CategoryList gets set with:[HttpPost] [CompressContent] public ActionResult List(MessageListViewModel model) { InitializeViewModel(model); busEntry entryBus = new busEntry(); var entries = entryBus.GetEntryList(model.QueryParameters); model.Entries = entries; model.DisplayMode = ApplicationDisplayModes.Standard; model.CategoryList = AppUtils.GetCachedCategoryList(); return View(model); } The AppUtils.GetCachedCategoryList() method gets the cached list or loads the list on the first access. The code to load up the list is housed in a Web utility class. The method looks like this:/// <summary> /// Returns a static category list that is cached /// </summary> /// <returns></returns> public static SelectListItem[] GetCachedCategoryList() { if (_CategoryList != null) return _CategoryList; lock (_SyncLock) { if (_CategoryList != null) return _CategoryList; var catBus = new busCategory(); var categories = catBus.GetCategories().ToList(); // Turn list into a SelectItem list var catList= categories .Select(cat => new SelectListItem() { Text = cat.Name, Value = cat.Id.ToString() }) .ToList(); catList.Insert(0, new SelectListItem() { Value = ((int)SpecialCategories.AllCategoriesButRealEstate).ToString(), Text = "All Categories except Real Estate" }); catList.Insert(1, new SelectListItem() { Value = "-1", Text = "--------------------------------" }); _CategoryList = catList.ToArray(); } return _CategoryList; } private static SelectListItem[] _CategoryList ; This seemed normal enough to me - I've been doing stuff like this forever caching smallish lists in memory to avoid an extra trip to the database. This list is used in various places throughout the application - for the list display and also when adding new items and setting up for notifications etc.. Watch that ModelBinder! However, it turns out that this code is clearly causing a problem. It appears that the model binder on the [HttpPost] method is actually updating the list that's bound to and changing the actual entry item in the list and setting its selected value. If you look at the code above I'm not setting the SelectListItem.Selected value anywhere - the only place this value can get set is through ModelBinding. Sure enough when stepping through the code I see that when an item is selected the actual model - model.CategoryList[x].Selected - reflects that. This is bad on several levels: First it's obviously affecting the application behavior - nobody wants to see their drop down list values jump all over the place randomly. But it's also a problem because the array is getting updated by multiple ASP.NET threads which likely would lead to odd crashes from time to time. Not good! In retrospect the modelbinding behavior makes perfect sense. The actual items and the Selected property is the ModelBinder's way of keeping track of one or more selected values. So while I assumed the list to be read-only, the ModelBinder is actually updating it on a post back producing the rather surprising results. Totally missed this during testing and is another one of those little - "Did you know?" moments. So, is there a way around this? Yes but it's maybe not quite obvious. I can't change the behavior of the ModelBinder, but I can certainly change the way that the list is generated. Rather than returning the cached list, I can return a brand new cloned list from the cached items like this:/// <summary> /// Returns a static category list that is cached /// </summary> /// <returns></returns> public static SelectListItem[] GetCachedCategoryList() { if (_CategoryList != null) { // Have to create new instances via projection // to avoid ModelBinding updates to affect this // globally return _CategoryList .Select(cat => new SelectListItem() { Value = cat.Value, Text = cat.Text }) .ToArray(); } …}  The key is that newly created instances of SelectListItems are returned not just filtered instances of the original list. The key here is 'new instances' so that the ModelBinding updates do not update the actual static instance. The code above uses LINQ and a projection into new SelectListItem instances to create this array of fresh instances. And this code works correctly - no more cross-talk between users. Unfortunately this code is also less efficient - it has to reselect the items and uses extra memory for the new array. Knowing what I know now I probably would have not cached the list and just take the hit to read from the database. If there is even a possibility of thread clashes I'm very wary of creating code like this. But since the method already exists and handles this load in one place this fix was easy enough to put in.

  • Technical Article: Oracle Magazine Java Developer of the Year Adam Bien on Java EE 6 Simplicity by Design

    - by janice.heiss(at)oracle.com
    Java Champion and Oracle Magazine Java Developer of the Year, Adam Bien, offers his unique perspective on how to leverage new Java EE 6 features to build simple and maintainable applications in a new article in Oracle Magazine. Bien examines different Java EE 6 architectures and design approaches in an effort to help developers build efficient, simple, and maintainable applications.From the article: "Java EE 6 consists of a set of independent APIs released together under the Java EE name. Although these APIs are independent, they fit together surprisingly well. For a given application, you could use only JavaServer Faces (JSF) 2.0, you could use Enterprise JavaBeans (EJB) 3.1 for transactional services, or you could use Contexts and Dependency Injection (CDI) with Java Persistence API (JPA) 2.0 and the Bean Validation model to implement transactions.""With a pragmatic mix of available Java EE 6 APIs, you can entirely eliminate the need to implement infrastructure services such as transactions, threading, throttling, or monitoring in your application. The real challenge is in selecting the right subset of APIs that minimizes overhead and complexity while making sure you don't have to reinvent the wheel with custom code. As a general rule, you should strive to use existing Java SE and Java EE services before expanding your search to find alternatives." Read the entire article here.

  • Start a Mapping or Process Flow from OWB Browser

    - by Dong Ruirong
    Basically, we start a Mapping or Process Flow from Oracle Warehouse Builder (OWB) Design Client. But actually we can also start a Mapping or Process Flow from OWB Browser. This paper will introduce the Start Report first and then introduce how to start/rerun a Mapping or Process Flow from OWB Browser. Start Report Start Report is used to start an execution of a Mapping or Process Flow. So there are two kinds of Start Report: Mapping Start Report (See Figure 1) and Process Flow Start Report (See Figure 2). Start Report shows the Mapping or Process Flow identification properties, including latest deployment and latest execution, lists all execution parameters for the Mapping or Process Flow, which were specified by the latest deployment, and assigns parameter default values from the latest deployment specification. You can do a couple of things from Start Report: Sort execution parameters on name, category. Table 1 lists all parameters of a Mapping. Table 2 lists all parameters of a Process Flow. Change values of any input parameter where permitted. For some parameters, selection lists are provided. For example, Mapping’s parameter Audit Level has a selection list. Reset all parameter settings to their default values. Apply basic validation to parameter values before starting an execution. Start the Mapping or Process Flow, which means it is executed immediately. Navigate to Deployment Report for latest deployment details of the Mapping or Process Flow. Navigate to Execution Job Report for latest execution of current Mapping or Process Flow Link to on-link help Warehouse Report Page, Deployment Report, Execution Report, Execution Schedule Report and Execution Summary Report. Figure 1 Mapping Start Report Table 1 Execution Parameters and default values for a Mapping Category Name Mode Input Value System Audit Level In Error Details System Bulk Size In 1000 System Commit Frequency In 1000 System EXECUTE_RESUME_TASK In FALSE System FORCE_RESUME_OPTION In FALSE System Max No of Errors In 50 System NUMBER_OF_TIMES_TO_RETRY In 2 System Operating Mode In Set Based Fail Over to Row Based System PARALLEL_LEVEL In 0 System Procedure Name In main System Purge Group In WB Figure 2 Process Flow Start Report Table 2 Execution Parameters and default values for a Process Flow Category Name Mode Input Value System EVAL_LOCATION In   System Item Key In-Out   System Item Type In PFPKG_1 Start a Mapping or Process Flow To navigate to Start Report, it’s better to login OWB Browser with Control Center option; if not, after logging in OWB Browser, go to Control Center first. Then you can follow the ways introduced in this section to navigate to Start Report. One more thing you need to pay attention to is that you are not allowed to deploy any Mappings and Process Flows from OWB Browser as it’s not supported. So it’s necessary to deploy the Mappings and Process Flows first before starting them from OWB Browser. If you have deployed a Mapping or Process Flow but have not started it, please navigate from Object Summary Report or Deployment Schedule Report to Start Report. 1. Navigating from Object Summary Report to Start Report Open the Object Summary Report to see all deployed Mappings and Process Flows. Click the Mapping Name or Process Flow Name link to see its Deployment Report. Select the Start link in the Available Reports tab for the given Mapping or Process Flow to display a Start Report for the Mapping or Process Flow. The execution parameters have the default deployment-time settings. Change any of the input parameter values as required. Click Start Execution button to execute the Mapping or Process Flow. 2. Navigating from Deployment Schedule Report to Start Report Open the Deployment Schedule Report to see deployment details of Mapping and Process Flow. Expand the project trees to find the deployed Mappings and Process Flows. Click the Mapping Name or Process Flow Name link to see its Deployment Report. Select the Start link in the Available Reports tab for the given Mapping or Process Flow to display a Start Report for the Mapping or Process Flow. The execution parameters have the default deployment-time settings. Change any of the input parameter values as required. Click Start Execution button to execute the Mapping or Process Flow. Re-run a Mapping or Process Flow If you have executed a Mapping or Process Flow, you can navigate from Object Summary Report, Deployment Schedule Report, Execution Summary Report or Execution Schedule Report to Start Report. 1. Navigating from the Execution Summary Report to Start Report Open the Execution Summary Report to see all execution jobs including Mapping jobs and Process Flow jobs. Click on the Mapping Name or Process Flow Name to see its Execution Report. Select the Start link in the Available Reports tab for the given Mapping or Process Flow to display a Start Report for the Mapping or Process Flow. The execution parameters have the default deployment-time settings. Change any of the input parameter values as required. Click Start Execution button to execute the Mapping or Process Flow. 2. Navigating from the Execution Schedule Report to Start Report Open the Execution Schedule Report to see list of all executions of Mapping and Process Flow. Click on the Mapping Name or Process Flow Name to see its Execution Report. Select the Start link in the Available Reports tab for the given Mapping or Process Flow to display a Start Report for the Mapping or Process Flow. The execution parameters have the default deployment-time settings. Change any of the input parameter values as required. Click Start Execution button to execute the Mapping or Process Flow. If the execution of a Mapping or Process Flow is successful, you will see this message from the Start Report: Start Execution request successful. (See Figure 3) Figure 3 Execution Result You can also confirm the execution of the Mapping or Process Flow by referring to Execution Report of the current Mapping or Process Flow by clicking the link in the Available Reports tab for the given Mapping or Process Flow. One new record of execution job details is added to Execution Report of the Mapping or Process Flow which shows the details of the execution such as Start Time, Elapsed Time, Status, the number of records selected, inserted, updated, deleted etc.

  • Oracle Australia Supports MS Sydney to Gong Ride by Chris Sainsbury

    - by user769227
    What is the Sydney to Gong Ride? The Gong Ride is a one of a kind fundraising event. You can pedal 90 km from Sydney to Wollongong on any day of the year but it's only on the first Sunday of November that you'll experience the camaraderie, fellowship, unity, safey, scenery and sense of achievement for pedalling in support of people living with MS. Well done to the 22 members of the Oracle Sydney to Gong ride on Sunday 6 November. For many, this was the first time riding over distance – officially a 90km event, by GPS about 84km. The event started in Sydney Park, Newtown. We left in a few separate groups between 6.30 and 7.30am – and finished with times between 2 hours 45 mins and 6 hours. With 10,000 riders there was a lot of congestion at the start but that soon thinned out as we left Sydney. It was a great spring day for the event but at 34 degrees it was getting pretty warm once we left the shade of the Royal National Park and carried on over the Sea Cliff bridge and down the coast road towards Wollongong. Unfortunately Dan managed to get himself a facial scrub when someone clipped his front wheel on the descent from Bald Hill lookout. No major incidents thankfully and Dan soldiered on. Most importantly everyone had a good time (even Dan) and we raised $5,800 for Multiple Sclerosis Australia. In total more than $3.7m was raised for this good cause.

  • Work Item Visualizer for TFS 2010 - New Extension

    - by MikeParks
    I released another new extension to the Visual Studio Gallery again today called Work Item Visualizer for TFS 2010. I've only heard positive things about it so far, hopefully it stays that way :) Basically, it creates a diagram of all work items linked to a work item ID which the user specifies in a search box. This extension was coded using DGML (the same graph rendering language used for the Visual Studio 2010 Architecture Tools). It was pretty cool getting a chance to create something using some of the newest technology out there. Well, I just wanted to throw a blog up to get the word out on it a little more. If you're using Visual Studio 2010 with Team Foundation Server 2010, feel free to check it out! Thanks everyone. Download Link: http://visualstudiogallery.msdn.microsoft.com/en-us/a35b6010-750b-47f6-a7a5-41f0fa7294d2   What it does: ·         Creates a DGML graph to visualize linked TFS Work Items by entering a Work Item ID in the toolbar search box   How it benefits you: ·         Allows you to easily analyze the hierarchy of your TFS Work Items ·         Gain the ability to perform basic risk/impact analysis when creating or editing Work Items ·         Great for meetings in the case that you need to discuss the entire scope of linked Work Items ·         Easier project planning ·         Eliminates the need to create TFS queries or reports to view tree of Work Items ·         Easily lets you see the entire tree of work items linked to the one you’re working on   Navigation Tips: ·         Use Ctrl + Mouse Wheel Scroll to zoom in and out ·         Use Ctrl + Left Mouse click (and hold) to move document around ·         Right click on DGML area for more options (Like copy image or viewing in groups) ·         Clicking on each node highlights that node and the links connected to it ·         Colors in the legend can be changed ·         When work item nodes are deleted, the view is automatically updated ·         Double clicking on work item node will open up the Work Items URL   Try it out on work items that have several of links and let us know what you think. A big thanks goes out to everyone working on the http://visualization.codeplex.com/ project for publishing the source code on CodePlex which really helped me learn how DGML (Directed Graph Markup Language - New to Visual Studio 2010 Architecture Tools) works!    - Mike

  • Ideas for my MSc project and Google Summer of Code 2011

    - by Chris Wilson
    I'm currently putting together ideas for my master's project which I'll be working on over the summer, and I would like to be able to use this time to help Ubuntu in some way. I have the freedom to come up with pretty much any project in the field of software development/engineering provided it Is a substantial piece of software (for reference, I will be working on it for five full months) Solves a problem for more people than just myself I was hoping to use this project as an opportunity to get some experience with the underbelly of Linux, so that I can mention on my CV that I have 'experience in developing for *NIX in C++', which I'm noticing more and more companies are looking for these days, probably because stuff's moving to cloud servers and that's where Linux rules the roost. My problem is that, since I don't have the experience to begin with, I'm not sure what to do for such a project, and I was wondering if anyone could help me with this. I've noticed from Daniel Holbach's blog that Ubuntu participated in the Google Summer of Code 2010, and that project ideas for that can be found here. However, I have not been able to find anything related to Ubuntu and GSoC 2011, but I have noticed from the GSoC timeline that the list of mentoring organisations will not be published until March 18th. I have two questions here. Has Ubuntu applied to be a part of Summer of Code 2011, and what is the status of the 2010 project list linked to earlier. Were they all implemented or are there still some that can be picked up now, should I not participate in GSoC? I'd like to do something for Ubuntu, but I'd rather not spend my time reinventing the wheel.
